No permeability found yet at St. Vincent and the Grenadines geothermal site

Heat was successfully found after the first well was drilled at the geothermal exploratory site at Bamboo Range, in Saint Vincent and the Grenadines, though permeability remains yet to be found.

“Possibly if we are lucky in well Two, we will come back in well One and try to fix that so we will get permeability. But this is exploration and we don’t know exactly what is down there, so this is normal for the first well,” Reykjavik Geothermal’s Thorleifur Finnsson told SVGTV.

Permeability of the bedrock is an essential element of the geothermal plant’s performance. This is because the thermal energy extraction procedures happen when heat is transferred from hot rocks into the surrounding circulating fluid. This flow through the rock is itself dependent on the permeability of the bedrock.

Further exploratory drilling is scheduled to determine permeability in other wells.
